Quick Answer

Amana furnaces are all natural gas furnaces. They come in three different types: modulating, variable-speed and multi-speed. Amana also provides the choice of standard-efficiency or high-efficiency models.

Amana furnaces contain a Million-Air heat exchanger with stainless steel tubes and wrinkle bend technology that maximizes heat transfer to the home. The modulating furnaces have self-calibrating gas valves that modulate performance from 35 percent to 100 percent. Units with variable-speed motors are designed to heat the home quickly, quietly and efficiently, and units with multi-speed motors are durable, reliable and quiet.

Annual Fuel Utilization Efficiency is a measurement of the percentage of energy converted into heat when gas is burned in the furnace. Standard-efficiency furnaces have an 80 percent AFUE or better and high-efficiency furnaces have an AFUE of 90 percent or better. Amana's high-efficiency models range from 92 percent AFUE to 97 percent AFUE. Some of these models offer either single stage or two-stage thermostats. These units should lead to a lower heating bill compared to electric furnaces or older, less-efficient gas furnaces.

Maytag Corporation owns the brand name Amana and licenses it to Goodman Company to manufacture units for sale in the United States. HVAC contractors provide and install these furnaces in homes.
